Hello,
I'm posting this for a friend, because his phone is "dead" and he is unable to post himself.
Earlier this year he brought a Galaxy SII from a second-hand phone shop, and it's worked fine up until now. He updated the ROM to the official 4.1.2 and since then it's had issues connecting to his home WiFi (unrelated, but it lead me to suspect the ROM) but it connects everywhere else. Then yesterday his phone just went blank and turned on again - the boot sound played at the touch buttons lit up for a moment and then faded as with a normal boot. But the screen was blank apart from several white spots, and a load of coloured pixels. I saw it myself today, and the colour of the pixels is random, although usually red or green, and the phone gets incredibly hot about a minute after turning on.
Is this a ROM fault, or could there be something more serious to it?
Just a shot in the dark, as I've never owned a Samsung, but could it be the "sudden death" bug that they allegedly have?
Thanks
Does it go to recovery? Factory reset. If not does it go to download mode?

I'm not sure - I think I managed to get it into the bootloader, but there's no way to tell because there is nothing on the screen but the white dots and random pixels. All I did notice was that when I removed the battery and turned it on again even more pixels appeared. We only went by the sound and touch lights, so it appeared to boot, but we don't even know if it switched straight off again

you are not sure ? did you try to go into recovery or download mode ? shutdown the phone first
Recovery = Volume up button + Home button + Power button
Download mode = Volume down button + Home button + Power button
Press vol+and home button and power button till it boots to recovery. Keep them all pressed down till it boots. If not try vol- home and power till it boots to download mode. Has he dropped it?

We tried that, and the touch lights came on but with no boot sound. The screen didn't change, just white dots and pixels, but it was working fine the day before.

Tried both, the screen just did the same thing and the phone got very hot very fast, and he said he hasn't dropped it at all, but that someone in his family may have, he's not totally sure because nobody admitted to using his phone.
Screen is prob broken. Pixels on it..not good. No recovery or download mode..really bad. For it too get really hot really fast may be a mb problem. Send it to service centre

Okay, thank you! He tried calling them and getting a quote, but the guy on the other end didn't seem to know what to do, and the man who owned the shop he brought it from offered to repair it, but for almost double what it cost him to buy the phone.
Thank you!
No problem mate. Get a second hand one. Prob be cheaper to do that now the s4 is out. Mb cost alot.

please remove the battery for like 10 minutes, wait a little bit, then try to go into recovery or download mode,
if that doesn't work, try this:
1.Press the key combination for recovery
2.Samsung logo appears - hold the buttons pressed.
3.Prompt disappears shortly - you still hold the buttons.
4.Samsung logo appears again - hold the buttons still pressed.
5.Count to 3 & let go, dont press the buttons anymore.
After 1 - 2 sec farther the Samsung logo disappears and the recovery starts maybe, i did that on my old i9100

Thank you, but that hasn't had any effect. Still a blank screen with white dots and thousands of coloured pixels. Thank you for all of your help though!

i got s3, suddenly it started to reboot itself all the time, what i see is only the samsung logo and then black, and samsung again.
the funny thing is that when i put the battery in, it automaticly start with this loop.
during the loop, when i press home+volume up, i can see the cwm screen for two seconds, and then it reboot again.
if i press home+voulume down, i see the warning in the stock recovery, but when i press volume up, nothing changed, and eventually after two seconds it reboots again.
i tried to connect it to my pc, but it dosen't show it in device manager, and have no indication that i connected it.
also, when i connect it the charger, i see circle, and then a battery for a brief second, and then the circle again.
is it simple hardware problem (stuck power button? even though it seem okay, but it may explain the automatic turn on), or half SDS?
anyway, are there any recommondations? i have'nt flashed it recently or anything like it.

as i wrote before, i can enter to both recovery modes (volume up or volume down) for something like two seconds, i can't do anything in it.
if i try to get to download mode (home and volume down) i see the warning, but either i press volume up or down, it reset itself.

the regular, about flashing custom roms, if i want to continue press volume up, restart, volume down.
either way, it restarts.
any way it is the power button stuck in 1 mode?
If phone starts on battery insertion, before you push the button then yes, power button is shorted out.

Try leaving the battery out overnight/long time, it helped when I got my phone stuck in a bootloop. But that was due to oc/uv...did you try something risky, causing it to bootloop?
no, it was in regular use, nothing risky.
yesterday i dissassembled it and checked with multimeter, it seem that the power button shorting the circuit, so i ordered a new one, going to be a surgical operation...

MY KERNEL CRASHED. I was minding my own buisness, downloading 6 or so apps (probably not a good idea) and then i opened on of the apps (called unpossible. my phone's (LG Optimus G E970) screen went black and suddenly i was looking at a screen with the text at the top saying "Kernel Crash!"
the whole screen is black except for the white text.
the only options are to go into download mode, reboot, and fast reboot using the volume up key, volume down key, and power buttons respectfully. i tried each one and nothing so far has happened. personally i think this is REALLY BAD and it should be fixed.
SO FREAKING HELP ME. would the full text help? please help me :crying::crying::crying::crying:
My rom is MIUI 4.3.something and it says something like demigod crash handler. I have Philz touch recovery installed.
No big deal unless it happens repeatedly. Volume key functions are reversed from what it says on the screen. I think it says volume down to reboot iirc. Hit volume up.

Ok never ran into one that wouldn't reboot. Can you get it to force-reboot by holding the power button for 10 seconds or so?

Is there any software or commands I could use to diagnose my phone over USB? The screen is black, even during boot (no logos), but the phone is still working in the background. The notification LED blinks normally, menu and back button lights up when pressed, and it even rings when someone calls, though I can't see who it is b/c of the black screen. The screen is not cracked or damaged, and I didn't drop it, so not sure why this is happening. I want to test the GPU or other components before I put down a lot of money for a new screen and it no resolve the issue.
Phone is a rooted SM-N910V that has been working great for 3 months.
Thank you!

Hi , try with key kombination .
1. Make sure your phone is OFF
2.Now Press toghether Vol + and power button and hold like that until second vibration (reboot)
3. If that doesn't work try with another combination .
Vol - and Power button
Vol + & Home button & Power button for about 10 second
Vol - & Home button & Power button for about 10 second
Good Luck

Thanks for the suggestions, though I have already tried all those plus other things.
I've left the battery out for over a day, removed sim card, held power button in to drain any residue power.
I'm lost as to why all of sudden the black screen. Hoping there's a way to test the phone to confirm if its the lcd or something else like the gpu chip. On a laptop you could plug a monitor in the vga port, don't guess phones have this option

I read that the phone was rooted so maybe that custom rom has some bug and that way you get black screen .
Try to flash him back to stock firmware and see if the problem is solved .
It is just rooted on the standard firmware, I didn't install any custom firmwares. But I was wondering if I could possibly reflash it from a backup I made with twrp. I cant get to recovery, well actually I could if I new the exact steps since everything works, I just cant see crap.
Is this even possible or is there another way to access twrp over the usb?

Sideloading latest update to Pixel 6, got to "reboot" phase and rebooted. This time another "reboot" option came up "cancel, latest update failed to complete". Without thinking I "rebooted" and now have a phone sitting here with a black screen and the word "Google" in bright colors. It has been this way for over an hour and doesn't respond to any button presses.
1st time in this situation - suggestions appreciated - 1st time posting here - hope I did it right
Enter recovery and flash the full factory image using adb.
Hold power button for about 30 sec.
Thanks for the replies
Phone seems to be locked - no response from any button, or button combo pushing - have tried all.
I think this phone is bricked

I think you have to hold the power button until it hurts your finger. That's what I have to do on my Fossil to get it to come back on when it dies. Make sure it's plugged in also.
I held the power button and several other button combos - nothing - phone is dead - new one ordered - thanks for the replies.

Mine was sitting at the Google screen yesterday too after flashing some modules, this is the only way I got out of it and into fastboot. Might be too late for you but maybe it helps someone else since JUST holding Power Up doesn't do anything.
Power + volume up should shut it down
When the screen goes black press power and vol down, that'll bring you to bootloader.
When it was at the "GOOGLE" screen I tried power + volume up, power + volume down, just power, just volume up, just volume down - nothing.. At this point I declared the phone dead and took the screen off . This was my 1st time taking a cell phone apart.
I appreciate all the replies I got to my situation, lots of knowledge on this forum
